O Chemistry problem
« on: November 30, 2010, 11:34:14 PM »
2-methylbutene   (reacting in the presence of H2SO4)   -->  2-methylbut-1-ol


What does the mechanism for this look like?

The place to start is figuring out where the alkene will get protonated. You can do that by thinking about forming the most stable carbocation.

Educt is not properly named (position of double bond has to be specified). Name of product is also wrong spelled.

Yeah ... It should be 2-methylbutan-2-ol

first bond shifts...then H+ attacks negative charge ... then lone pair of O from H20  attacks  + charge and then H+ leaves from H2O.

But yeild of this reaction would be very less.
